Lying:Withinnthenlower portion of the valveeasing 17 is a fixed sleeve25'1having a top Wall 26 carrying a Central guide 27 for the dependingstem 28 of a ball valve 29 that t v normally oecupiesthevalveseatlS endshuts Fig. 2 is a similar' view shoivingthe'parts ofil the flow ofliquid.` Opposite sides of the sleeve *arev Yformed With openings 30that register With` the openings 20, 21and 23, Yand the Walls of thesleeve between said opend when the latter is in its raised position(Fig. p

2). The short arm of this lever carries a counterweight 35, andthefreeend of its long arm normally engages a shoulder .36 formed on a triggermember 37 that is pivoted at 38 between a pair of upstanding lugs 39`carried'by the movable sleeve 22; said trigger having an inwardlyextending arm 40 from the free endof which is suspended a float l1movable in and guided by the lower portion of the fixed sleeve member25.

YThe normal position of the parts is as shown in Fig. l. When a bottleis raised into engagement with the lower end `of the movable sleeve22'a11d the latter is raised to the extent permitted by the adjustablestop nut 24, the valve 29 is raised, as shown in Fig. 2, and the liquidflows into the bottle, the air in the latter finding a ready vent aroundthe lower end of the valve casing and through the openings 23 and 20.rIhe stop 24, by adjustment up .or down, variesi the extent of openingof the valve and consequently'the rapidity of the flow. At this time theweight of the float il and arm 40 of the trigger is slightly butsuiiiciently in excess of the'downward thrust of the open valve tomaintain the parts in the relative positions shown in Fig. 2. `When thebottle has been lled to the required height, the raising of the ioat bythe liquid in the bottle tilts the trigger, moving the supportingshoulder 36 thereof away. from the free end of the valve-supportinglever 34, whereupon the parts instantly assume the relative positionsshown in Fig. 3 wherein the valve 29 is closed, and the flow of liquidto the bottle is shut off. As the bottle is withdrawn the movable sleeve22 descends, lowering the i opening parts in a purely mechanicalbottlellingvalve mechanism is a new result so far as we areaware,'andconstitutes an important feature of our present invention. ItVwill also be observed that `the weight or thrust of the valve, whenopen, is applied through the lever 34 to the trigger 37 at a point Qnthe opposite side ofthe pivotof the latter from the oat, thus tending toraise the latter. The fioat 1s, of course, heavy enough to resist thistendency (eX- Vcept when raised by the liquid in the bottle) but thisarrangement makes practicable the use of a comparatively small iioat,and renders the mechanism very sensitive and uniform in its action,resulting in a uniform filling of the bottles served thereby.

While we have shown and described a particular form of mechanism foraccomplishing the stated objects of the invention, it will bemanifest tothose skilled in the art that the same may be modified in detail withinthe operative principle of the invention and without sacrificing any ofthe advantages secured thereby. We therefore do not limit the inventionto the exact mechanism shown-and described, but include all equivalentsthereof which come within the purview and spirit of the appended claims.

We claim: i l. In a bottle-filling device of the character described,the combination of a valve casing having a valve seat, a valve movabletowardand from said seat, a Vvertically movacter described, thecombination of a valveV easing having a valve seat, a valve movabletoward and fromsaid seat, a vertically mov-` able sleeve on said valvecasing adapted to be lifted by a bottle when brought into fillingposition, and a `float-controlled valveopening mechanism carried by saidsleeve, said mechanism including normally engaged elements which operateto open said valve when said sleeve is raised, disengage under theaction of the float and permit the valve to close when the liquid in thebottle reaches a predetermined height and automatically rengageeachother when said Vsleeve descends.
